Re: HDMI Inputs Have No Signal - Samsung UN65MU6290

If your native one is BN94-12696B, then you should replace it with BN94-12696B with the letter "B", with another letter "C" or "D" there may be incompatibility of the panel itself (matrix).

Re: Toshiba 32AV933G stuck on stby

Check all the voltages on the motherboard inductors, maybe there is no voltage or the voltage on them is too low.

Re: Monitor Audio RSW-12 Plate Amp Popping/Crackling

You need to check these tracks, they may be broken (this happens over time after the Chinese glue, even metal (copper) starts to corrode under it).

Re: EuropAce EWC 913 Wine Cooler power board fuse blow /shorted

I do not have such a board, all the photos that I posted from the Internet, so all measurements and replacement of components are up to you, if the color rings should be 100 Om, then change to 100 Om.
